acionamento de ações de animação e ações de objeto de mídia

A request may be received to trigger an animation action in response to reaching a bookmark during playback of a media object. In response to the request, data is stored defining a new animation timeline configured to perform the animation action when playback of the media object reaches the bookmark. When the media object is played back, a determination is made as to whether the bookmark has been encountered. If the bookmark is encountered, the new animation timeline is started, thereby triggering the specified animation action. An animation action may also be added to an animation timeline that triggers a media object action at a location within a media object. When the animation action is encountered during playback of the animation timeline, the specified media object action is performed on the associated media object.
